To all whom it may concern:

- Be it known that I, 'OTAKER NEDVIDEK, a, citizen of the United States, and a resident of Milwaukee, in the county of Clackamas and State of Oregon, have invented an Improved Yarn Condenser and Polisher for Cordage-Spinning. Machines, of whichthe following is a specification.

My invention is an improvement in socalled nippers or machines designed for treating, that is to say, condenslng and rounding and polishing hemp yarn or slivers preliminary: to spinning for making ropes and cordag The invent-ion is embodied in the construction, arrangement, and combination of parts hereinafter described, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the apparatus, the hinged yoke carrying one of the condensing dies being shown open as re quired for re-threading. Fig. 2 is a vertical cross section on the line 2'2 of Fig. ,3.

Fig. 3 is a central vertical longitudinal section. Flg. 4 1s a vertical cross section on the line 4el of Fig. 3. Fig. 5 is a perspective view of the finishing blocks or dies. Fig.

6 is a perspective view of the stem and block of the upper condensing die. Fig. 7 is a perspective View of the condensing shell dies separated from other parts and from each other. v

The working parts of the apparatus or nipper are attached to, and supported upon a pedestal 1 having a horizontal flanged base 2 adapted to be screwed to afloor or other fixed support. A trumpet or funnelshaped guide 3 is fixed vertically on the pedestal, it being secured to the upwardly projecting arms of the same by means of screws fil -see Figs. 1 and 4.

Directly rear of the trumpet guide 3 are arranged the two initial or preliminary condensing dies 5 and 6 and, in rear of the latter, are the finishing: blocks or dies 7. As shown in Fig. 7, the dies 5 and G are constructed in what-may be termed she'll form, being struck up and formed from a steel plate and constructed with interned side flanges 5 and a closed front or head 5 the dies being thus left open at one endto adapt them for sliding engagement with holders of corresponding form. One of the said holders is a: block 8-see Fig.

6-which is provided-with a stem 9 adapted .to slide in'a vertical hollow guide illsee l'1ig. 3the latter being an attachment of a curved yoke l1see Fig. 1-which is pivoted to the pedestal at 12 and adapted to be swung open for re-threading the nipper.

; The front portion of each die 5, 6, is formed with a tapered indent or depression 5 which, when the dies are together, as shown 1n F1 s 3 and 4, form a tapered guide throng which the hemp yarn or sliver is drawn, and, by pressure of the dies thereon,

thesame is compressed and condensed. A splral spring 13 is arranged 1n the tubular v guide 10 of the yoke 11, and a set-screw 14 and jam-nut l5 serve as means for ad- ;justing the tension of the spring, or, in other words, regulating the pressure between 'the dies 5 and 6. In practice, the lower die '6 may be provided with a spring pressed jstein in the same way as the upper one, but I do not deem it necessaryto illustrate the construction, since it would be practi-' cally a duplication.

As shown in Fig. 4, the lower die 6 is applied to a part 4? oft-he pedestal, it being understood that it is shaped substantially the same as the block or holder 8 to which theupper die 5 is applied. The free end of the yoke 11 carrying the upper die is -provided with a spring-pressed lever catch 16 which is adapted to look at 17 with a I shoulder on one of the arms of the pedestal.

Thus the yoke occupies in use the locked position indicated in Figs. 3 and l, but when it is required to l e-thread the machine or to obtain access to the dies 5 and 6 for removing them and substituting others, upon operating the catch 16, the yoke may be thrown back asshown in Fig. 1.

The finishing dies 7 are elongated blocks having a tapered score 7 extending longitudinally in their faces, the same forming, when the blocks are put together as in Fig.

1, a tubular score 'or guide in which the hemp yarn or sliver 1S rounded and polished to the degree required preparatory to twisting or splnning. .The score blocks are held down upon the horizontal top portion of the pedestal by means of hooks or dogs 18 whose prongs enter side openings in the blocks and are provided with sleeves adapted to slide on a. rod 19 arranged horizontally and projccting laterally from the pedestal 1.. The ends of the rod are provided with nuts 20, for compressing the spiral springs 21 which encircle the, rod and are arranged between .the nuts and the flanged heads of the hooks.

It apparent that, by drawin back the dogs-18, they may be' disengage from the rounding dies 7 and the latter removed to erator' desires to thread the machine, t e

catch 16 being released, the yoke 10 may be swung back, as shownin Fi 7, and, the yarn or sliver being introduce through the central hole in the trumpet guide 3, it is drawn over the lower condensing die 6 and then down between the rounded corners of the blocks 7 and into the score of the same. The initial dies 5 and 6 com ress, condense, and to .a certain extent polish the yarn or sliver, and the finishing dies or blocks 7 round, polish, and finish the sliver while hein twisted in the usual way.

t will be seen that the machine is thus especially adapted for easy, convenient, and rapid threading and re-threading and that the adapation of the dies 5, 6, and 7 for removal and re lacement is an important advantage in t is class of machines. The s ring 13 acting upon the condensing dies a lows them to yield for the passage of knots or'lumps of lint or other foreign material lpassing with the yarn or sliver, so that the tter is not broken or unduly strained. What I claim is 1. The initial condensers composed of opposite jaws, detachable shell dies a 'plied to the latter and formed with tapers indents and inturned side flangesadapted to clasp the side portions of the jaws, one end of the dies bein open and the front closed and abutting t e aws when the dies are adjusted in place, as described.

- 2. The combination with a supporting frame, a trumpet guide, and condensin dies of a yoke hinged to the frame and a apted to swing transversely ofthe same, said yoke having a hollow guide, a die holder provided with a stem, adapted to slide in said guide, an expansion spring pressing on said stem, means for adjustin the tension of the same, and a spring catc for securing the yoke closed, as described.

3. The combination with a supporting frame, of finishing dies consisting 0 blocks arranged opposite each other and having their adjacent inner sides scored longitudiinner corners rounde and a spring attachment for pressing the blocks together, as described. I

4. The combination with a su porting frame and finishin dies slidable aterally thereon toward an from each other, and a horizontal rod held in the frame below the dies, of dogs detachably' engaging said blocks and having tubular portions adapted to slide on said rod, expansion-springs applied to the dogs and rods and means for adjusting the tension of the same, as described.
